UNITED STATES HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented Feb. 13, 1906.

Application filed October 23, 1903. Serial No. 178,274.

To all whom, it may concern:

Be it known that I, FRED J. WOQDHEAD, a citizen of the United States,residing at Bakersfleld, in the county of Kern, State of California,have invented new and useful Improvements in Hydrocarbon-Burners, ofwhich the following is a specification.

My invention relates to a burner designed to lurn crude petroleung -oilby the use of steam; and the object thereof is to provide an efficientburner for that purpose in which the sup ly of oil to a certain extentis automatical y regulated by the steam-pressure. I accomplish thisobject by the burner described herein and illustrated in the accompanying drawings, in which-- Figure 1 is a longitudinal central sectionof my burner. Figs. 2 and 3 are respectively a plan and a sideelevationf the burner-ti In the drawings, A is the casing of tl fe steam-chamberof my burner, which is made ofordinary pipe of asu'itable size, dcending upon the capacity of the burner, on tlie front end of which isscrewed the burner-tip B.

This burner-tip is divided by partition 0 into two chambers, the lowerone of which constitutes the steanr-chamber D and the upper one Econstitutes the oil-chamber thereof. Partition C has an internallythreaded hole ,0 in the rear portion thereof, into which is screwed thefront end of the casing F of the oil-chamber, which extends rearwardlythrough the steam-chamber and'through T- fitting G, which is screwedupon the rear end 3 5 of the steam-chamber casing. Fitting G has anoutlet H, which rovides means for connecting the steam-c amber by apipe(not shown) with a sup ly. On the rear end of the casing of the oi-chamber is screwed a re- 40 duc-er I. which is externally threaded andscrews into one of the outlets of the T-fitting G. This reducer extendsrearwardlv of the fitting G, and upon it is screwed a T-fitting J,

having outlet K for the reception of an oil-- pipe (not shown) ,toconnect it with an oilsupply. In the other outlet of the fitting-J isscrewed a hollow cylinder L, the rear end of which is externallythreaded for the reception of a gland M, which, with washer N and epacking O, formsa stuffing-box around stem P, which is enlarged withincylinder L, as shoun, and externally threaded to fit the internalthreads of the cylinder, and thereby on the rotation of the stem to giveit a longitudinal movement in the cylinder. On the rear end of this stemis a hand-wheel R, by means of which the stem may be rotated.

stem passes through the oil-chamber, and its front end terminates in avalve-stopper S, which is adapted to pass into ort T in partition C andregulate the size t ereof and en tirely close the same, if desired. Thesteam.- chamber is rovided with the semicircular port U and t eoil-chamber is rovided with a semicircular port V directly a ove thesteamport and separated therefrom by the end of partition O. Extendingthrough the top of the casing of the oil-chamber is'the regulating-plugW, which passes therethrough in screw-threaded contact therewith and isvertically movable to re ulate the size ofthe oilport and may entire yclose the same, if de-.

sired.

laced wit the tip extending into the comustion-chamber of a fire-box(not shown) and is connected up with suitable oil and steam su plies,(not shown,) which are regulated in t. e usual well known manner tosupply the oil and steam necessary to produce the desired flame. In theregulation of the oil and steam supplies valve-stopper S is o ened topermit a. portion of the steam mm t e steam-chamber to pass" into theoil-charm. ber, and thereby create a given back pressure on the 'oilflowing into chamber E, which must have suflicient pressure to force itinto chamber E against the back pressure caused by the steam passinginto chamber E through port T. Thls back ressure is taken intoconsideration in regu ating the quantities of steam and oil which areadmitted into the burner. Thereafter should the steamprefisure vary thequantity of oil and steam passing out of the burner-tip will also vary.If the steam- 'ressure rises owing to its greater force, it chamber E ofthe burner-tip, and thereby prevent as much Oil entering therein asenter at the time of the regulation, thus reducirxg' the heating powerofthe flame produced by the burner. On the other hand, should the pressureof the steam fall below normal the back pressure of the steam lpassingthrough port T into chamber E wil be less than it was at the time of theregulation, and more In the operation of my burner the same is I createa greater back pressure in oil will flow into chamber E and out of portV 7 steaimplressure of the boiler, it being understood t at the burneris used for producing steamin the boiler which furnishes steam to theburner.

Having described my invention, What I claim as new, and desire to secureby Letters Patent, is

l. A hydrocarbonburner comprising a steam-chamb er a burner-tip on theouter end thereof, said burner-ti having two chambers therein separatedy a partition; ports inthe chambers of said burner-ti one directly aboveand the other directl be ow the front end of the partition; an o ichamber within said steam chamber and communicating with the upperchamber of the burner-tip; aport in thepartition between the chambers ofthe burner-tip disposed therein opposite the center of the oil-supplychamber; a valvestopper adapted to control the port in said partltion,said valve-stopper having a stem extending rearwardly through theoil-chamber and having means to give-said stem a longitudinal movementin said chamber.

2. A hydrocarbon-burner comprising an oil and a steam chamber eachhaving an independent outlet-port, said chambers being incommunicatidfi'with each other near the outlet-ports; means to controlsaid communi cation, means to create a back pressure by forming passagesrespectively for the oil and,

atomizmgfluid, said assages having separate outlets, and one of t e Wals having an orifice therein leading from the fluid-passage to theoil-passage to communicate t e pressure of the fluid to theoilpassageQwhereby automatically to regulate the oil-discharge, and

means for regulating the area of the oil discharge or outlet.

In witness that I claim the foregoing I have FRED J. WOODHEAD.
